🟢12a - Direct Method of Interpolation: Linear Interpolation

In this lesson, we shall be doing polynomial interpolation.
Interpolation is a method that is used to derive a simple function from a given discrete data set that passes through the provided data points. In other words, interpolation is a method to construct new data points from the range of a given discrete data set of known data points.
Extrapolation on the other hand has to do with obtaining or estimating y values that correspond to an x value that is outside the range of the provided data set.

The direct method of interpolation is based on the theory that:
Given n+1 data points, there is one and only one polynomial that passes through the provided data set.
We shall solve an example of Linear Interpolation
